Tokenizer¶
Motivation¶
There is no possible standard how CSV files are described. There is no schema, so every file you get may look completely different. This rules out one single strategy to tokenize a given line in your CSV data.
Imagine a situation, where a column delimiter is also present in the column data like this:
FirstNameLastName;BirthDate
"Philipp,Wagner",1986/05/12
""Max,Mustermann",2014/01/01
A simple string.Split
with a comma as column delimiter will lead to wrong data, so the line
needs to be split differently. And this is exactely where a Tokenizer
fits in.
So a Tokenizer
is used to split a given line of your CSV data into the column data.
Available Tokenizers¶
StringSplitTokenizer¶
The StringSplitTokenizer
splits a line at a given column delimiter.
Philipp,Wagner,1986/05/12
Is tokenized into the following values:
Philipp
Wagner
1986/05/12
RFC4180Tokenizer¶
The RFC4180 proposes a specification for the CSV format, which is commonly accepted. You can use
the RFC4180Tokenizer
to parse a CSV file in a RFC4180-compliant format.
Example¶
Imagine a RFC4180-compliant CSV file with Person Names should be parsed. Each Person has a Name
,
Age
and Description
. The Name
and Description
may contain the column
delimiter and also double quotes.
Name, Age, Description
"Michael, Chester", 24, "Also goes by ""Mike"", among friends that is"
"Robert, Willliamson", , "All-around nice guy who always says hi"
The following example shows how to use the RFC4180Tokenizer
for the given example data.

{
public SampleEntityMapping()
{
MapProperty(0, x => x.Name);
MapProperty(1, x => x.Age);
MapProperty(2, x => x.Description);
}
}
[Test]
public void RFC4180_CsvParser_Integration_Test()
{
// Use a " as Quote Character, a \\ as Escape Character and a , as Delimiter.
var options = new Options('"', '\\', ',');
// Initialize the Rfc4180 Tokenizer:
var tokenizer = new RFC4180Tokenizer(options);
// Now Build the Parser:
CsvParserOptions csvParserOptions = new CsvParserOptions(true, tokenizer);
SampleEntityMapping csvMapper = new SampleEntityMapping();
CsvParser<SampleEntity> csvParser = new CsvParser<SampleEntity>(csvParserOptions, csvMapper);
var stringBuilder = new StringBuilder()
.AppendLine("Name, Age, Description")
.AppendLine("\"Michael, Chester\",24,\"Also goes by \"\"Mike\"\", among friends that is\"")
.AppendLine("\"Robert, Willliamson\", , \"All-around nice guy who always says hi\"");
// Define the NewLine Character to split at:
CsvReaderOptions csvReaderOptions = new CsvReaderOptions(new[] { Environment.NewLine });
var result = csvParser
.ReadFromString(csvReaderOptions, stringBuilder.ToString())
.ToList();
Assert.AreEqual(2, result.Count);
Assert.AreEqual(true, result.All(x => x.IsValid));
Assert.AreEqual("Michael, Chester", result[0].Result.Name);
Assert.AreEqual(24, result[0].Result.Age);
Assert.AreEqual("Also goes by \"Mike\", among friends that is", result[0].Result.Description);
Assert.AreEqual("Robert, Willliamson", result[1].Result.Name);
Assert.AreEqual(false, result[1].Result.Age.HasValue);
Assert.AreEqual("All-around nice guy who always says hi", result[1].Result.Description);
}
}
}
RegularExpressionTokenizer¶
The RegularExpressionTokenizer
is an abstract base class, that uses a regular expression
to match a given line. So if you need to match a line with a regular expression, you have to implement
this base class.
The QuotedStringTokenizer
is a good example to start with.
QuotedStringTokenizer¶
The QuotedStringTokenizer
is an implementation of a RegularExpressionTokenizer
. It uses
a (rather complicated) regular expression to leave data in a double quotes (""
) untouched, so a line
like:
"Philipp,Wagner",1986/05/12
Is tokenized into the following values:
Philipp,Wagner
1986/05/12
Example¶
Imagine a CSV file contains a list of persons with the following data:
FirstNameLastName;BirthDate
"Philipp,Wagner",1986/05/12
""Max,Mustermann",2014/01/01
The first name and the last name are using a comma, which is the same character as the column delimiter.
So the file can’t be tokenized by only splitting at the column delimiter with the default
StringSplitTokenizer
.
This is where the QuotedStringTokenizer
is needed!
The Tokenizer
is set in the CsvParserOptions
.
using NUnit.Framework;
using System;
using System.Linq;
using System.Text;
using TinyCsvParser.Mapping;
using TinyCsvParser.Tokenizer.RegularExpressions;
namespace TinyCsvParser.Test.Tokenizer
{
[TestFixture]
public class TokenizerExampleTest
{
private class Person
{
public string FirstNameWithLastName { get; set; }
public DateTime BirthDate { get; set; }
}
private class CsvPersonMapping : CsvMapping<Person>
{
public CsvPersonMapping()
{
MapProperty(0, x => x.FirstNameWithLastName);
MapProperty(1, x => x.BirthDate);
}
}
[Test]
public void QuotedStringTokenizerExampleTest()
{
CsvParserOptions csvParserOptions = new CsvParserOptions(true, new QuotedStringTokenizer(','));
CsvReaderOptions csvReaderOptions = new CsvReaderOptions(new[] { Environment.NewLine });
CsvPersonMapping csvMapper = new CsvPersonMapping();
CsvParser<Person> csvParser = new CsvParser<Person>(csvParserOptions, csvMapper);
var stringBuilder = new StringBuilder()
.AppendLine("FirstNameLastName;BirthDate")
.AppendLine("\"Philipp,Wagner\",1986/05/12")
.AppendLine("\"Max,Mustermann\",2014/01/01");
var result = csvParser
.ReadFromString(csvReaderOptions, stringBuilder.ToString())
.ToList();
// Make sure we got 2 results:
Assert.AreEqual(2, result.Count);
// And all of them have been parsed correctly:
Assert.IsTrue(result.All(x => x.IsValid));
// Now check the values:
Assert.AreEqual("Philipp,Wagner", result[0].Result.FirstNameWithLastName);
Assert.AreEqual(1986, result[0].Result.BirthDate.Year);
Assert.AreEqual(5, result[0].Result.BirthDate.Month);
Assert.AreEqual(12, result[0].Result.BirthDate.Day);
Assert.AreEqual("Max,Mustermann", result[1].Result.FirstNameWithLastName);
Assert.AreEqual(2014, result[1].Result.BirthDate.Year);
Assert.AreEqual(1, result[1].Result.BirthDate.Month);
Assert.AreEqual(1, result[1].Result.BirthDate.Day);
}
}
}
FixedLengthTokenizer¶
Sometimes you need to parse a CSV file, that is defined by fixed width columns. The FixedLengthTokenizer
addresses this problem and makes
it possible to define columns by their start and end position in a given file. The FixedLengthTokenizer
takes a list of
FixedLengthTokenizer.ColumnDefinition
, which define the columns of the file.
Example¶
In the following example the textual input is split into two columns. The first column is between index 0 and 10, and the second column is between the
index 10 and 20. You can see, that these values build the list of ColumnDefinition
, which are passed into the FixedLengthTokenizer
.

Taiwan bookstore Eslite releases 2019 bestseller list
Self-help books are the most popular genre, with talk show host Kevin Tsai top of the list
by Karen Liao(CNA photo)
TAIPEI (Taiwan News) — The top 10 bestsellers at Eslite bookstore for 2019 were announced on Tuesday (Nov. 19), with self-help books among the most popular.
It is evident, according to Eslite, that people are hoping to empower themselves by reading, reported CNA. The Eslite top 10 list was collated from data gathered from Nov. 1, 2018 to Oct. 31, 2019.
The number one bestseller was Taiwan talk show host Kevin Tsai’s (蔡康永) “The Emotional Quotient Lesson of Kevin Tsai: Live for Yourself for One Time.” Li Chin’s (李勁) “Poor Self-expression is a Weakness of 99% of People 2” (99%的人輸在不會表達2) ranked second.
Ranked 10th was Taiwanese internet celebrity Ken Chung’s (鍾明軒) “I Decide Who I Am: In a Life Full of Negativity, I Do Not live on Someone Else’s Terms” (我決定我是誰). This details his struggles with being bullied for his gender expression and eventually learning to overcome the challenges.
Carol Bolt’s “The Book of Answers,” a field guide to Pokemon; Peter Su’s, “Accompaniment is the Most Luxurious Present in the World” (陪伴，是世上最奢侈的禮物); the queen of romantic suspense Tess Gerritsen’s, “The Apprentice;” Higashino Keigo’s masterpiece of mystery, “The Murder Scene in the Air;” Michelle Obama’s “Becoming;” Wang Yun’s (王薀) “Post Meditation (靜坐之後),” are the books ranked from third to ninth.


 The process of creating a black and white image reminds me of creating pixel artwork. Pixel art, with its inherent restrictions, requires anti-aliasing, dithering, and careful linework in order to make a smooth, crisp, and professional image. Rules must be followed within these techniques, making pixel art a rather rigid medium to work with.
The same goes for black and white work; luckily, there aren’t any mathematical restrictions on the same calibre as pixel art. As there are imposed restrictions, clever methods need to be used to achieve the same amount of detail that a coloured image contains. Yet, B&W details are markedly of a different nature, containing a quality that is unknown and foreign to coloured works. Working with two colours (and, the third colour that stems naturally, gray) is the definition of working minimally, but creating deep impressions.
Coloured work is liberated - black and white is unyielding. Working in B&W has taught me a lot of tricks; I’m still discovering more everytime I work in this medium.
Colour
We live in a world of colour, so it’s only natural that humans desire to make colours close to the ones produced by nature (although, colour is relative). Generally speaking, most of us see more or less the same colours. The sky is blue, the grass is green … the trees are brown, you’re yellow, and I’m gray, etc. I enjoy working with colour because it’s an excellent way to show people what you mean, because for most individuals, colour is associated with a feeling or experience, or what have you. Whether or not you and your friend agree that red invokes imagery/words of power and passion, the fact is, colour is definitive in providing a connection from your brain to the world beyond your self. You could be a logical and technical person with a strong distaste for feelings in art, but your brain will make some sort of connection when you see (a) colour(s) in a painting.
Sketches
The best part of making work! The work before it was complete. It’s a real treat for me to view an admired illustrator’s sketches. It shows me how they got from the beginning to the end, and gives me confidence that I too, can finish my work. Sketches aren’t just restricted to visual works; video games, music, writing and much more all require the ‘first beginnings’ and gives you an idea of what the creator(s) were going for, and why.
Personally, the very first sketch I draw is generally infantile in appearance. It’s shocking that I start out with little details and somehow manage to finalize the idea. Guess the brain fills in the rest.
Lastly, I’m always updating my portfolio with new artwork. So check up every week or two and there’ll most likely be a newly added picture.

Spotlight on foreign interference at universities
by Finbar O'MallonAustralian universities will have to name their research partners and financial donors under new rules to safeguard against foreign interference.
The federal government directive follows concerns about China’s influence in Australia and a 2018 cyber attack on the Australian National University, which was only revealed in June.
Political ties of research collaborators, the end goal of the research and the objectives of foreign governments will all be scrutinised under the changes.
The new rules were drawn up by universities and intelligence experts from the Department of Home Affairs and the Australian Security Intelligence Organisation.
Under the new guidelines, universities will have to consider the “dual-use” of their research.
Earlier this year, University of Queensland researchers were found to be collaborating on facial recognition technology used by the Chinese government to surveil ethnic Uighurs.
The paper detailing the new guidelines does not list any penalties for universities found to be breaching the new rules.
Federal Education Minister Dan Tehan said he was confident in the new guidelines, which he said would ensure universities understood the risks they faced.

Once upon a time there was a prince who wanted to marry a princess; but she would have to be a real princess. He travelled all over the world to find one, but nowhere could he get what he wanted. There were princesses enough, but it was difficult to find out whether they were real ones. There was always something about them that was not as it should be. So he came home again and was sad, for he would have liked very much to have a real princess.
One evening a terrible storm came on; there was thunder and lightning, and the rain poured down in torrents. Suddenly a knocking was heard at the city gate, and the old king went to open it.
 But, good gracious! what a sight the rain and the wind had made her look. The water ran down from her hair and clothes; it ran down into the toes of her shoes and out again at the heels. And yet she said that she was a real princess.
Well, we'll soon find that out, thought the old queen. But she said nothing, went into the bed-room, took all the bedding off the bedstead, and laid a pea on the bottom; then she took twenty mattresses and laid them on the pea, and then twenty eider-down beds on top of the mattresses.
On this the princess had to lie all night. In the morning she was asked how she had slept.
"Oh, very badly!" said she. "I have scarcely closed my eyes all night.  It's horrible!"
Now they knew that she was a real princess because she had felt the pea right through the twenty mattresses and the twenty eider-down beds.
Nobody but a real princess could be as sensitive as that.
So the prince took her for his wife, for now he knew that he had a real princess; and the pea was put in the museum, where it may still be seen, if no one has stolen it.
There, that is a true story.

Introduced in Office Excel 2003 this is a FRT record. It is used to extend a FRT record that is larger than the maximum record size. This record differs from the CONTINUEFRT with an additional ref range. This is because the limitation of Excel 2000 on FRT causing the CONTINUEFRT to be lost, round-tripping only the parent FRT record.
Hence, for all new features starting from Office Excel 2003, this CONTINUEFRT11 must be used to write a large feat record instead of CONTINUEFRT . This ensures a continued record will round-trip with its FRT record through Excel 2000 and Excel 2002.
Special note : to ensure the record will round-trip through Excel 2000 correctly, the grbit field of the CONTINUEFRT11 must be zero or the Ref.colLast must not be equal to 0xFFFF (the limitation of Excel 2000 FRT handling). Office Excel 2003 sets this grbit to be 0, and the ref to be NULL.

For a while now, I've considered going for Ubuntu Membership, and I've decided now is the time. I feel that my contributions to the community are significant and that Ubuntu has become a significant part of my life. I'd like to ask anyone who feels comfortable supporting me to post on my Ubuntu wiki page at https://wiki.ubuntu.com/Matir. I appreciate your support in the community.


The Schwarzschild radius is the radius that defines the edge, or the
event horizon, of a
black hole, the point past which nothing can escape once it goes through. The radius is defined as
R_S = \frac{2GM}{c^2} , where G is the Gravitational Constant, M is the mass of the
black hole, and c is the speed of light. For example, the Schwarzschild radius of the Sun is about 3km, if one were to compress the mass of the Sun into a region less than that, it would inmediatelly collapse into a
black hole.

Erik is the secretary in charge of organizing Team 2's work in Github!
I'm in my last year at San Francisco State University as a computer science major. I started programming as a hobby when I was 19 and immediately switched my major. My favorite languages to program in are C/C++ but i'm also proficient in Java and Python. I've been cooking and working part time jobs to support myself through school and I hope to one day work for NASA or SpaceX.
Most SFSU students know the Linux based file system project from CSC 415 and hated it. I thought it was one of the most interesting projects i've worked on because it showed me how little I knew about something I use everyday. I will never take copy and paste command for granted again.
The Manly P. Hall collection is a project that will last most of my life. I want to collect and preserve all of the philosophers work. For a more detailed explanation, click here.


Parmitano tells us why repairs in space are a lot like heart surgery
by EuronewsEuronews space correspondent and European Space Agency (ESA) astronaut Luca Parmitano has sent the latest instalment of Space Chronicles, a series in which he documents his experiences on the International Space Station (ISS) over a six-month period. On this episode, Parmitano is joined in the airlock by NASA astronaut Andrew Morgan. Together they'll be repairing an Alpha Magnetic Spectrometer in space.
The Alpha Magnetic Spectrometer sits outside the space station. The thermal control system onboard the Alpha Magnetic Spectrometer has failed and the astronauts will be going outside to fix it, using a series of spacewalks.
Parmitano explains the task ahead:
"We’re going to open up the system, we’re going to cut the current tubes - just like you do when you’re doing a heart transplant - and then we’re going to take the new pump - the new 'heart' - and then we will take new tube and install those tubes on to the ones that exist and start circulating the cooling system that we brought up from space. So, in a way, it’s open-heart surgery in space on a very complex system."
Magnetic spectrometers are hard to fix on the ground and Parmitano and Morgan have the added challenge of doing it in space, wearing restrictive and pressurised spacesuits.
They'll also be carrying four or five big bags of tools that they'll be using during the repair.
"It is very much like open-heart surgery," Morgan says. "I'm not a heart surgeon but I am a physician, so I thought there's a lot of interesting analogies here."
One of Morgan's roles is to be managing all these tools while Parmitano does most of the cutting and swaging.
- In collaboration with the European Space Agency (ESA).

Press release
New stats show more 16- to 18-year-olds in education, employment or training since comparable records began.
Figures released today (25 June 2014) reveal the proportion of 16- to 18-year-olds not in education, employment or training ( NEET ) is at the lowest level since comparable records began 20 years ago.
The statistics also show the number of 16- to 18-year-olds NEET has dropped by more than a quarter since the end of 2009. Education Secretary Michael Gove credited the fall on the government reforms to education and training.
The figures show that for England at the end of 2013:
The government’s reforms mean that more and more young people are being given the chance to fulfil their potential - through studying or training, embarking on an apprenticeship or traineeship or entering the world of work.
Education Secretary Michael Gove said:
I am delighted to see more young people earning or learning. The figures showing how many 16-, 17- and 18-year-olds are not in education employment or training are at their lowest level since comparable records began.
Today’s figures show our education reforms are helping to deliver the government’s long-term economic plan. More young people are better prepared than ever before for the world of work or further study. That means greater economic security for young people and their families across the country.
Skills and Enterprise Minister Matthew Hancock said:
These figures confirm our radical education reforms are improving the prospects of thousands of young people across England.
A clearer link from education to work, more rigour, and record numbers of apprenticeships have all helped give more young people what they need to get the jobs available.
It’s a vital part of our long-term economic plan and our moral mission to help all young people in Britain to fulfil their potential.
The government has a package of measures to help young people get the best possible start in life. This includes:

Rodrigues Converts a rotation matrix to a rotation vector or vice versa
dst = cv.Rodrigues(src)
[dst,jacobian] = cv.Rodrigues(src)
src
.src
.The function transforms a rotation matrix in the following way:
theta <- norm(r)
r <- r/theta
R = cos(theta) * I + (1 - cos(theta)) * r * r^T + sin(theta) * A
A = [0, -rz, ry; rz, 0, -rx; -ry, rx, 0]
Inverse transformation can be also done easily, since
sin(theta) * A = (R - R^T) / 2
A rotation vector is a convenient and most compact representation of a rotation matrix (since any rotation matrix has just 3 degrees of freedom). The representation is used in the global 3D geometry optimization procedures like cv.calibrateCamera, cv.stereoCalibrate, or cv.solvePnP.


Location
We have three guesthouses waiting for you in the town of Lengyeltóti. All ouf our houses have a very destict decor and have been designed with different gust types in mind. Even though all the places are a different world they are very close phisically and in a very easily walkable distance.


Consider the following coordinate pairs:
jQuery.map( POINTS, PAIR ).join( "\\qquad" )
Which of those pairs is not graphed below?
(POINTS[FORGOTTEN].join( ", " ))
PAIR( POINTS[0] )
PAIR( POINTS[1] )
PAIR( POINTS[2] )
PAIR( POINTS[3] )
PAIR( POINTS[4] )


z-math
A simple module for operations on arbitrarily large integers, because sometimes 64-bit floats don't quite cut it. In future versions, I plan to add support for operations on Z_n (i.e. modular arithmetic and multiplication), as well as some common number theory algorithms such as calculating gcd, lcm, etc.
Usage
To download the package simply run npm install --save z-math
. Then just require it into your app like follows, and you are good to go: var integer = require('z-math')
Once you have the package imported you can create new integers with the integer(n)
command where n is a regular integer in Javascript (technically a floating point number).
To convert an integer, say a
, back to a JavaScript float use a.toFloat()
or use it in the context of a mathematical operation, e.g. a + 5
.
To convert an integer, say b
, to a string, use b.toString()
, or use it in the context of a string e.g. console.log('The integer is: ' + b)
Operations
Then the remaining operations are defined as follows:
Add 2 integers: integer.add(a, b)
Subtract 2 integers: integer.subtract(a, b)
Multiply 2 integers: integer.multiply(a, b)
Get the quotient when dividing 2 integers: integer.quotient(a, b)
Get the modulus when dividing 2 integers: integer.mod(a, b)
Find a to the power of b: integer.pow(a, b)
To test equality/inequality there are a number of functions: integer.greaterThan
, integer.lessThan
, integer.equal
, integer.notEqual
, integer.greaterThanEqual
, integer.lessThanEqual
Note that you can use integer.lte
and integer.gte
as shortcuts for integer.lessThanEqual
and integer.greaterThanEqual
respectively.
All of these operations return new integers and leave the original ones untouched.

Matrix Orientation
and Angular Displacement
Orientation is given by a rotation from a known reference orientation
(identity or home orientation).
This rotation amount is called angular displacement.
Orientation will be used in for parent/child relationships
Angular displacement will be used for source/destination relationships
The distinction between the two is similar as the distinction between
points and vectors, mathematically equivalent but not identical conceptually.
Matrix Form
$
\left[
\begin{smallmatrix}
m_{11} && m_{12} && m_{13}
\\
m_{21} && m_{22} && m_{23}
\\
m_{31} && m_{32} && m_{33}
\end{smallmatrix}
\right]
$
First row is x, second is y, third is z
Advantages of Matrix Form
-
Rotation of vectors is immediately available: use a matrix to
rotate between object and inertial space.
-
Format used by graphics APIs: you can do other forms internally
but must convert into matrices at some point.
Advantages of Matrix Form
-
Concatenation of multiple angular displacements: if we know
orientation of obj A to obj B and obj B to obj C, then we know
obj A to obj C.
-
Matrix inversion: easy to compute the opposite angular displacement.
Due to rotation matrix being orthogonal, trivial to compute transposing the matrix.
Disadvantages of Matrix Form
-
Matrices take more memory: nine numbers needed instead of only three.
If we have an animation with 10 parts, at 15 Hz, that's 150 orientations/second.
With 32-bit floating point numbers: $15*9*32/8 = 5400$ bytes/frame.
Euler Angles would only be 1800 bytes.
Disadvantages of Matrix Form
-
Difficult for humans: too many #s, all between -1 and 1.
-
Matrices can be malformed: six degrees of redundancy (nine numbers
when only three are needed).
Disadvantages of Matrix Form
How can we end up with a bad matrix?
-
Suppose we have a matrix that contains a scale, skew, or reflection.
There is no definition of an orientation of an object affected by these.
Any non-orthogonal matrix is not a well-defined rotation matrix.
-
We may get bad data from an external source (modeling software, etc)
-
Floating-point round off errors. This is known as matrix creep.

--- layout: archive title: Zulip Chat Archive permalink: /stream/113488-general/topic/composing.20tactics.html ---
Suppose I prove a goal using by repeat {constructor}
. What is the syntax for creating a new def of type tactic unit
that does the same thing? Do I have to drop down into using the non-interactive tactics?
I guess handling the context and goals explicitly in a do
block isn't so bad, but I was wondering if this is the correct way to do it
ahh, figured it out. it's just interactive.repeat interactive.constructor
. I didn't know about the itactic
type
1) Go to the definition of tactic.interactive.repeat
and look how its defined. I don't know if we have any documentation on how to write interactive tactics beyond the ICFP paper. Short version: when you use begin foo bar end
, lean looks for a definition named tactic.interactive.foo
. The type of the arguments of tactic.interactive.foo
determine how the arguments to the tactic are parsed. For example, itactic
tells lean to parse a tactic block in curly braces.
2) You can use `[repeat {constructor}]
to use interactive tactic syntax outside of begin-end blocks.

THE CRUCIBLE
A film review by Walter Frith
Copyright 1997 Walter Frith
Arthur Miller's play from the 1950's entitled 'The Crucible' was a very timely play indeed in wake of the McCarthy hearings in the United States designed to root out communists and which many of its critics termed a "witch hunt." The setting for this movie is Salem, Massachusetts in 1692 and the root of this play is literally a witch hunt involving adultery, conscience, betrayal and relentless evil. Daniel Day-Lewis stars as John Proctor, a man trying to save the honor and life of his patronizing wife (Joan Allen) who is a woman of moral conduct and devotion to her husband. An inquest conducted by a British magestrate (Paul Scofield) in a chilling and commanding performance which should snag him an Oscar nomination seeks to root out the presence of Satan not only in Proctor's wife but presumably in the character of a young woman (Winona Ryder) and other members of her group who meet in secret ritual fashion. The penalty for being convicted of any association with Satan is death by hanging. Ryder's character had an adulterous affair with John Proctor and now seeks to destroy his marriage by aiding in the conviction of his wife all the while trying to prove her own innocence. Director Nicholas Hytner ('The Madness of King George') fashions an electrifying yet plain look to this film which is in keeping with Miller's story and the entire cast shines with emotion and passion. I was impressed with the way this movie was able to avoid any pretentious conclusion as it makes its point clearly and then exits appropriately. One of 1996's most well acted pieces.

Fuel imports exceed $ 180 m in one month
Within one month of this fiscal year, the fuel imports exceeded 180 million US dollars, down 29 million US dollars compared with the same period last year, said Khin Maung Lwin, Assistant Permanent Secretary of the Commerce Ministry.
From October 1 to 25 of 2019-20 fiscal year, the diesel import reached 112 million US dollars, down 18 million US dollars compared with the same period last year. During the same period, the pertrol imports amounted to 71 million US dollars, down 11 million US dollars.
During this month, the fuel imports amounted to 183 million US dollars.
According to Myanmar Fuel Importer, Distribution Association, the retail price of diesel was between Ks 910 and Ks 960 per liter and the whole sale price, between Ks 870 and Ks 885 per liter. The retail price of premium diesel was between Ks 920 and Ks 975 per liter and the whole sale price, between Ks 880 and Ks 900 per liter, on November 6.
The retail price of RON (92) was between Ks 820 and Ks 860 per liter and the whole sale price, between Ks 815 and Ks 820 per liter. The retail price of RON (95) was between Ks 920 and Ks 960 per liter and the whole sale price, between Ks 870 and Ks 880 per liter.
The fuel prices have increased by Ks 40 to Ks 65 per liter compared with the rates in the previous two months.
From January to May this year, the fuel prices increased by 160 to Ks 255 per liter. The fuel prices increased by Ks 25 to Ks 60 in January, Ks 40 in February, Ks 55 to Ks 80 in March and Ks 35 to Ks 65 in April this year. Since early June, the fuel prices have been on the delcine.

--- layout: post title: "The Lazy monad" description: "Lazy computations form a monad. An article for object-oriented programmers." date: 2022-05-30 5:34 UTC tags: [Software Design, Functional Programming] --- {% include JB/setup %}
{{ page.description }}
This article is an instalment in an article series about monads. A previous article described how lazy computations form a functor. In this article, you'll see that lazy computations also form a monad.
A monad must define either a bind or join function. In C#, monadic bind is called SelectMany
. You can define one as an extension method on the Lazy<T> class:
public static Lazy<TResult> SelectMany<T, TResult>( this Lazy<T> source, Func<T, Lazy<TResult>> selector) { return new Lazy<TResult>(() => selector(source.Value).Value); }
While the implementation seemingly forces evaluation by accessing the Value
property, this all happens inside a lambda expression that defers execution.
If x
is a Lazy<int>
and SlowToString
is a function that takes an int
as input and returns a Lazy<string>
you can compose them like this:
Lazy<string> y = x.SelectMany(SlowToString);
The result is another lazy computation that, when forced, will produce a string
.
Monads also enable query syntax in C# (just like they enable other kinds of syntactic sugar in languages like F# and Haskell). As outlined in the monad introduction, however, you must add a special SelectMany
overload:
public static Lazy<TResult> SelectMany<T, U, TResult>( this Lazy<T> source, Func<T, Lazy<U>> k, Func<T, U, TResult> s) { return source.SelectMany(x => k(x).Select(y => s(x, y))); }
This would enable you to rewrite the above example like this:
Lazy<string> y = from i in x from s in SlowToString(i) select s;
The behaviour is the same as above. It's just two different ways of writing the same expression. The C# compiler desugars the query-syntax expression to one that composes with SelectMany
.
In the introduction you learned that if you have a Flatten
or Join
function, you can implement SelectMany
, and the other way around. Since we've already defined SelectMany
for Lazy<T>
, we can use that to implement Flatten
. In this article I use the name Flatten
rather than Join
. This is an arbitrary choice that doesn't impact behaviour. Perhaps you find it confusing that I'm inconsistent, but I do it in order to demonstrate that the behaviour is the same even if the name is different.
The concept of a monad is universal, but the names used to describe its components differ from language to language. What C# calls SelectMany
, Scala calls flatMap
, and what Haskell calls join
, other languages may call Flatten
.
You can always implement Flatten
by using SelectMany
with the identity function.
public static Lazy<T> Flatten<T>(this Lazy<Lazy<T>> source) { return source.SelectMany(x => x); }
You could also compose the above x
and SlowToString
with Select
and Flatten
, like this:
Lazy<Lazy<string>> nested = x.Select(SlowToString); Lazy<string> flattened = nested.Flatten();
The flattened
value remains deferred until you force execution.
Apart from monadic bind, a monad must also define a way to put a normal value into the monad. Conceptually, I call this function return (because that's the name that Haskell uses). You don't, however, have to define a static method called Return
. What's of importance is that the capability exists. For Lazy<T>
in C# the idiomatic way would be to use a constructor, but the version of .NET I'm using for this code (this is actually code I wrote years ago) doesn't have such a constructor (newer versions do). Instead, I'll define a function:
public static Lazy<T> Return<T>(T x) { return new Lazy<T>(() => x); }
In other words, Return
wraps a pre-existing value in a lazy computation.
We need to identify the return function in order to examine the monad laws. Now that this is done, let's see what the laws look like for the Lazy monad, starting with the left identity law.
[Property(QuietOnSuccess = true)] public void LazyHasLeftIdentity(Func<int, string> h_, int a) { Func<int, Lazy<int>> @return = Lazy.Return; Lazy<string> h(int x) => Lazy.Return(h_(x)); Assert.Equal(@return(a).SelectMany(h).Value, h(a).Value); }
Like in the previous article the test uses FsCheck 2.11.0 and xUnit.net 2.4.0. FScheck can generate arbitrary functions in addition to arbitrary values, but it unfortunately, it can't generate lazy computations. Instead, I've asked FsCheck to generate a function that I then convert to a lazy computation.
In order to compare the values, the assertion has to force evaluation by reading the Value
properties.
In a similar manner, we can showcase the right identity law as a test.
[Property(QuietOnSuccess = true)] public void LazyHasRightIdentity(Func<string, int> f_, string a) { Func<string, Lazy<int>> f = x => Lazy.Return(f_(x)); Func<int, Lazy<int>> @return = Lazy.Return; Lazy<int> m = f(a); Assert.Equal(m.SelectMany(@return).Value, m.Value); }
As always, even a property-based test constitutes no proof that the law holds. I show it only to illustrate what the laws look like in 'real' code.
The last monad law is the associativity law that describes how (at least) three functions compose.
[Property(QuietOnSuccess = true)] public void LazyIsAssociative( Func<int, string> f_, Func<string, byte> g_, Func<byte, TimeSpan> h_, int a) { Lazy<string> f(int x) => Lazy.Return(f_(x)); Lazy<byte> g(string x) => Lazy.Return(g_(x)); Lazy<TimeSpan> h(byte x) => Lazy.Return(h_(x)); Lazy<string> m = f(a); Assert.Equal(m.SelectMany(g).SelectMany(h).Value, m.SelectMany(x => g(x).SelectMany(h)).Value); }
This property once more relies on FsCheck's ability to generate arbitrary pure functions, which it then converts to lazy computations.
The Lazy functor (which is also an applicative functor) is also a monad. This can be used to combine multiple lazily computed values into a single lazily computed value.
Next: Asynchronous monads.

I created brycemueller.com not only let you know more about me, but also to sharpen my skills as a Software Engineer. I love learning new things. So I thought, "Hey, what if I could build a website all by myself and learn new things along the way!" So here it is in all her glory!
Read about what's new on my blog
I believe that family is a very important part of life. Whether it's your real family or some close friends, they are who help you get through life. I have the pleasure of being a husband to a wonderful wife of 5 years and an amazing almost 4 year old daughter. They make life worth living!
We live in an era that surrounds us with technology. We use it everyday with our phones and computers. We use it in our homes and now even wear it on our bodies. I know for a fact that it will only become more important as time goes on, so why not embrace it and even try to shape the future ourselves.
As I have gotten older I have realized that keeping myself active and healthy is becoming more and more important. Myself and my family are all vegetarian and on a regular basis race 10k's and half-marathons. I believe that staying heathly I benefit myself, my family, and my employer.
"Excellence is doing ordinary things extraordinarily well" -John W. Gardner. I have attended FGCU for 4 years now and know this quote to be so true. I learned to accomplish assignments in a precise and timely manner. Receiving my bachelors degree in Software Engineering is no ordinary task but an exceptional honor.
My skills in Software Engineering were sharpened everyday in the classroom; however I grew as a engineer at home. Teaching myself outside the classroom and using the knowledge of each professor to perfect my craft has been truly amazing. I still have so much more to learn and have a thirst to keep growing.
I followed my love for technology and passion for teamwork right into Apple Retail. I am a trainer at the Apple store and have been with the company for almost 6 years. My time with Apple and its amazing people have taught me nothing is accomplished with out teamwork and communication.

I drive boats and do search and rescue but am studying to become a web developer. I will learn JavaScript, Python, and PHP on top of what I know now.
I enjoy writing front-end code with these technologies
